The Plato Program

Plato: a Program Library for the Analysis of 4d Nonlinear Transverse Motion

The PLATO (Perturbative Lattice Analysis and Tracking tOols) program, a program library for analyzing fourdimensional betatronic motion in circular particle accelerators is presented. The routines included in this library provide both the resonant and the nonresonant perturbative series that approximate nonlinear motion (normal forms); standard numerical tools such as the Lyapunov exponent, fre...

Populations are Multisets-PLATO

There are presently many and seemingly different optimization algorithms, based on unrelated paradigms. Herein we propose a framework to encompass those heuristics, providing a common working structure and a basis for their comparison. A formal de nition, based on the multiset formalism is presented. We also show how to express some common operators in our framework and we present some (partial...

Plato and Innatism

Plato and Divination

Plato uses the idea of divinatory knowledge as a metaphorical descriptor for a variety of kinds of daytime, waking knowing. What unites these examples is that they all include discussion of a kind of knowing that cannot account for itself, and that is tentative, imagistic and non-discursive. These metaphorical uses can further be illuminated by his more detailed discussion of divinatory knowled...

The Reliability of PLATO 1 Running Head: THE RELIABILTY OF PLATO Investigating the Reliability of Classroom Observation Protocols: The Case of PLATO

The reliability of the PLATO rubric is defined using Generalizability Theory and FACETS. Results from two G-Theory analyses reveal that the reliabilities of scores from individual PLATO items and the total score across all items are most strongly affected by the number of segments in which teachers’ performance is observed. For example, it is reported that a single rater should observe at least...
